ABSTRACT

Systems, computer program products, and methods are described herein for secure channel selection for multi-factor authentication using non-fungible electronic resources. The present invention is configured to receive, from a user input device, a request from a user to access resources; determine a first authentication channel for verification of user identity; trigger an authentication channel validation engine to validate the first authentication channel; retrieve authentication channel information associated with the first authentication channel; determine that the user has a non-fungible token (NFT) for the first authentication channel; retrieve, from one or more metadata layers of the NFT, authentication channel descriptors associated with the first authentication channel; compare the authentication channel information with the authentication channel descriptors to determine a match; determine that the first authentication channel is valid based on at least the match; and initialize verification of the user identity via the first authentication channel.

FIELD OF THE INVENTION

The present invention embraces a system for secure channel selection for multi-factor authentication using non-fungible electronic resources.

BACKGROUND

In the field of information security, access control is the selective restriction of access to a particular resource within a distributed network. Typically, general access control includes authentication, authorization, and review. The authentication portion of access control, among other things, includes user identity verification. In some embodiments, the identity verification process may be multi-factor authentication, i.e., require the user to present two or more pieces of evidence (or factors), depending on the type of access requested by the user. Each factor may be verified using a dedicated authentication channel. There is a need for a system for validating the authentication channel prior to using them for identity verification.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Where possible, any terms expressed in the singular form herein are meant to also include the plural form and vice versa, unless explicitly stated otherwise. Also, as used herein, the term “a” and/or “an” shall mean “one or more,” even though the phrase “one or more” is also used herein. Furthermore, when it is said herein that something is “based on” something else, it may be based on one or more other things as well. In other words, unless expressly indicated otherwise, as used herein “based on” means “based at least in part on” or “based at least partially on.” Like numbers refer to like elements throughout.

As used herein, an “entity” may be any institution employing information technology resources and particularly technology infrastructure configured for processing large amounts of data. Typically, these data can be related to the people who work for the organization, its products or services, the customers or any other aspect of the operations of the organization. As such, the entity may be any institution, group, association, financial institution, establishment, company, union, authority or the like, employing information technology resources for processing large amounts of data.

As described herein, a “user” may be an individual associated with an entity. As such, in some embodiments, the user may be an individual having past relationships, current relationships or potential future relationships with an entity. In some embodiments, a “user” may be an employee (e.g., an associate, a project manager, an IT specialist, a manager, an administrator, an internal operations analyst, or the like) of the entity or enterprises affiliated with the entity, capable of operating the systems described herein. In some embodiments, a “user” may be any individual, entity or system who has a relationship with the entity, such as a customer or a prospective customer. In other embodiments, a user may be a system performing one or more tasks described herein.

As used herein, a “user interface” may be any device or software that allows a user to input information, such as commands or data, into a device, or that allows the device to output information to the user. For example, the user interface includes a graphical user interface (GUI) or an interface to input computer-executable instructions that direct a processor to carry out specific functions. The user interface typically employs certain input and output devices to input data received from a user second user or output data to a user. These input and output devices may include a display, mouse, keyboard, button, touchpad, touch screen, microphone, speaker, LED, light, joystick, switch, buzzer, bell, and/or other user input/output device for communicating with one or more users.

As used herein, an “engine” may refer to core elements of an application, or part of an application that serves as a foundation for a larger piece of software and drives the functionality of the software. In some embodiments, an engine may be self-contained, but externally-controllable code that encapsulates powerful logic designed to perform or execute a specific type of function. In one aspect, an engine may be underlying source code that establishes file hierarchy, input and output methods, and how a specific part of an application interacts or communicates with other software and/or hardware. The specific components of an engine may vary based on the needs of the specific application as part of the larger piece of software. In some embodiments, an engine may be configured to retrieve resources created in other applications, which may then be ported into the engine for use during specific operational aspects of the engine. An engine may be configurable to be implemented within any general purpose computing system. In doing so, the engine may be configured to execute source code embedded therein to control specific features of the general purpose computing system to execute specific computing operations, thereby transforming the general purpose system into a specific purpose computing system.

As used herein, “authentication credentials” may be any information that can be used to identify of a user. For example, a system may prompt a user to enter authentication information such as a username, a password, a personal identification number (PIN), a passcode, biometric information (e.g., iris recognition, retina scans, fingerprints, finger veins, palm veins, palm prints, digital bone anatomy/structure and positioning (distal phalanges, intermediate phalanges, proximal phalanges, and the like), an answer to a security question, a unique intrinsic user activity, such as making a predefined motion with a user device. This authentication information may be used to authenticate the identity of the user (e.g., determine that the authentication information is associated with the account) and determine that the user has authority to access an account or system. In some embodiments, the system may be owned or operated by an entity. In such embodiments, the entity may employ additional computer systems, such as authentication servers, to validate and certify resources inputted by the plurality of users within the system. The system may further use its authentication servers to certify the identity of users of the system, such that other users may verify the identity of the certified users. In some embodiments, the entity may certify the identity of the users. Furthermore, authentication information or permission may be assigned to or required from a user, application, computing node, computing cluster, or the like to access stored data within at least a portion of the system.

It should also be understood that “operatively coupled,” as used herein, means that the components may be formed integrally with each other, or may be formed separately and coupled together. Furthermore, “operatively coupled” means that the components may be formed directly to each other, or to each other with one or more components located between the components that are operatively coupled together. Furthermore, “operatively coupled” may mean that the components are detachable from each other, or that they are permanently coupled together. Furthermore, operatively coupled components may mean that the components retain at least some freedom of movement in one or more directions or may be rotated about an axis (i.e., rotationally coupled, pivotally coupled). Furthermore, “operatively coupled” may mean that components may be electronically connected and/or in fluid communication with one another.

As used herein, an “interaction” may refer to any communication between one or more users, one or more entities or institutions, and/or one or more devices, nodes, clusters, or systems within the system environment described herein. For example, an interaction may refer to a transfer of data between devices, an accessing of stored data by one or more nodes of a computing cluster, a transmission of a requested task, or the like.

As used herein, “determining” may encompass a variety of actions. For example, “determining” may include calculating, computing, processing, deriving, investigating, ascertaining, and/or the like. Furthermore, “determining” may also include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory), and/or the like. Also, “determining” may include resolving, selecting, choosing, calculating, establishing, and/or the like. Determining may also include ascertaining that a parameter matches a predetermined criterion, including that a threshold has been met, passed, exceeded, and so on.

As used herein, a “resource” may generally refer to objects, products, devices, goods, commodities, services, and the like, and/or the ability and opportunity to access and use the same. Some example implementations herein contemplate property held by a user, including property that is stored and/or maintained by a third-party entity. In some example implementations, a resource may be associated with one or more accounts or may be property that is not associated with a specific account. Examples of resources associated with accounts may be accounts that have cash or cash equivalents, commodities, and/or accounts that are funded with or contain property, such as safety deposit boxes containing jewelry, art or other valuables, a trust account that is funded with property, or the like. For purposes of this invention, a resource is typically stored in a resource repository—a storage location where one or more resources are organized, stored and retrieved electronically using a computing device.

As used herein, a “resource transfer,” “resource distribution,” or “resource allocation” may refer to any transaction, activities or communication between one or more entities, or between the user and the one or more entities. A resource transfer may refer to any distribution of resources such as, but not limited to, a payment, processing of funds, purchase of goods or services, a return of goods or services, a payment transaction, a credit transaction, or other interactions involving a user's resource or account. Unless specifically limited by the context, a “resource transfer” a “transaction”, “transaction event” or “point of transaction event” may refer to any activity between a user, a merchant, an entity, or any combination thereof. In some embodiments, a resource transfer or transaction may refer to financial transactions involving direct or indirect movement of funds through traditional paper transaction processing systems (i.e. paper check processing) or through electronic transaction processing systems. Typical financial transactions include point of sale (POS) transactions, automated teller machine (ATM) transactions, person-to-person (P2P) transfers, internet transactions, online shopping, electronic funds transfers between accounts, transactions with a financial institution teller, personal checks, conducting purchases using loyalty/rewards points etc. When discussing that resource transfers or transactions are evaluated it could mean that the transaction has already occurred, is in the process of occurring or being processed, or it has yet to be processed/posted by one or more financial institutions. In some embodiments, a resource transfer or transaction may refer to non-financial activities of the user. In this regard, the transaction may be a customer account event, such as but not limited to the customer changing a password, ordering new checks, adding new accounts, opening new accounts, adding or modifying account parameters/restrictions, modifying a payee list associated with one or more accounts, setting up automatic payments, performing/modifying authentication procedures and/or credentials, and the like.

As used herein, a “distributed ledger” may refer to a consensus of replicated and synchronized data geographically shared across multiple nodes on a network. Without using a centralized data storage, each distributed ledger database replicates and saves an identical copy of the ledger. A distributed ledger may employ executing codes, also known as smart contracts, to manage transactions and store records of transactions among disparate participants in the distributed ledger-based network (DLN) without the need for a central authority.

As used herein, a “non-fungible token” or “NFT” may refer to a digital unit of data used as a unique digital identifier for a resource. An NFT may be stored on a distributed ledger that certifies ownership and authenticity of the resource, and as such, cannot be copied, substituted, or subdivided. In specific embodiments, the NFT may include at least relationship layer, a token layer, a metadata layer(s), and a licensing layer. The relationship layer may include a map of various users that are associated with the NFT and their relationship to one another. For example, if the NFT is purchased by buyer B1 from a seller S1, the relationship between B1 and S1 as a buyer-seller is recorded in the relationship layer. In another example, if the NFT is owned by O1 and the resource itself is stored in a storage facility by storage provider SP1, then the relationship between O1 and SP1 as owner-file storage provider is recorded in the relationship layer. The token layer may include a smart contract that points to a series of metadata associated with the resource, and provides information about supply, authenticity, lineage, and provenance of the resource. The metadata layer(s) may include resource descriptors that provides information about the resource itself (e.g., resource information). These resource descriptors may be stored in the same metadata layer or grouped into multiple metadata layers. The licensing layer may include any restrictions and licensing rules associated with purchase, sale, and any other types of transfer of the resource from one person to another. Those skilled in the art will appreciate that various additional layers and combinations of layers can be configured as needed without departing from the scope and spirit of the invention.

FIG. 1 illustrates technical components of a system for secure channel selection for multi-factor authentication using non-fungible electronic resources 100, in accordance with an embodiment of the invention. FIG. 1 provides a unique system that includes specialized servers and system communicably linked across a distributive network of nodes required to perform the functions of the process flows described herein in accordance with embodiments of the present invention.

As illustrated, the system environment 100 includes a network 110, a system 130, and a user input device 140. In some embodiments, the system 130, and the user input device 140 may be used to implement the processes described herein, in accordance with an embodiment of the present invention. In this regard, the system 130 and/or the user input device 140 may include one or more applications stored thereon that are configured to interact with one another to implement any one or more portions of the various user interfaces and/or process flow described herein.

In accordance with embodiments of the invention, the system 130 is intended to represent various forms of digital computers, such as laptops, desktops, video recorders, audio/video player, radio, workstations, servers, wearable devices, Internet-of-things devices, electronic kiosk devices (e.g., automated teller machine devices), blade servers, mainframes, or any combination of the aforementioned. In accordance with embodiments of the invention, the user input device 140 is intended to represent various forms of mobile devices, such as personal digital assistants, cellular telephones, smartphones, augmented reality (AR) devices, virtual reality (VR) devices, extended reality (XR) devices, and other similar computing devices. The components shown here, their connections and relationships, and their functions, are meant to be exemplary only, and are not meant to limit implementations of the inventions described and/or claimed in this document.

In accordance with some embodiments, the system 130 may include a processor 102, memory 104, a storage device 106, a high-speed interface 108 connecting to memory 104, and a low-speed interface 112 connecting to low speed bus 114 and storage device 106. Each of the components 102, 104, 106, 108, 111, and 112 are interconnected using various buses, and may be mounted on a common motherboard or in other manners as appropriate. The processor 102 can process instructions for execution within the system 130, including instructions stored in the memory 104 or on the storage device 106 as part of an application that may perform the functions disclosed herein, display graphical information for a GUI on an external input/output device, such as display 116 coupled to a high-speed interface 108, and/or the like. In other implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. Also, multiple systems, same or similar to system 130 may be connected, with each system providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system). In some embodiments, the system 130 may be a server managed by the business. The system 130 may be located at the facility associated with the business or remotely from the facility associated with the business.

The memory 104 stores information within the system 130. In one implementation, the memory 104 is a volatile memory unit or units, such as volatile random access memory (RAM) having a cache area for the temporary storage of information. In another implementation, the memory 104 is a non-volatile memory unit or units. The memory 104 may also be another form of computer-readable medium, such as a magnetic or optical disk, which may be embedded and/or may be removable. The non-volatile memory may additionally or alternatively include an EEPROM, flash memory, and/or the like. The memory 104 may store any one or more of pieces of information and data used by the system in which it resides to implement the functions of that system. In this regard, the system may dynamically utilize the volatile memory over the non-volatile memory by storing multiple pieces of information in the volatile memory, thereby reducing the load on the system and increasing the processing speed.

The storage device 106 is capable of providing mass storage for the system 130. In one aspect, the storage device 106 may be or contain a computer-readable medium, such as a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations. A computer program product can be tangibly embodied in an information carrier. The computer program product may also contain instructions that, when executed, perform one or more methods, such as those described above. The information carrier may be a non-transitory computer- or machine-readable storage medium, such as the memory 104, the storage device 104, or memory on processor 102.

In some embodiments, the system 130 may be configured to access, via the network 110, a number of other computing devices (not shown) in addition to the user input device 140. In this regard, the system 130 may be configured to access one or more storage devices and/or one or more memory devices associated with each of the other computing devices. In this way, the system 130 may implement dynamic allocation and de-allocation of local memory resources among multiple computing devices in a parallel or distributed system. Given a group of computing devices and a collection of interconnected local memory devices, the fragmentation of memory resources is rendered irrelevant by configuring the system 130 to dynamically allocate memory based on availability of memory either locally, or in any of the other computing devices accessible via the network. In effect, it appears as though the memory is being allocated from a central pool of memory, even though the space is distributed throughout the system. This method of dynamically allocating memory provides increased flexibility when the data size changes and allows memory reuse for better utilization of the memory resources when the data sizes are large.

The high-speed interface 108 manages bandwidth-intensive operations for the system 130, while the low speed controller 112 manages lower bandwidth-intensive operations. Such allocation of functions is exemplary only. In some embodiments, the high-speed interface 108 is coupled to memory 104, display 116 (e.g., through a graphics processor or accelerator), and to high-speed expansion ports 111, which may accept various expansion cards (not shown). In such an implementation, low-speed controller 112 is coupled to storage device 106 and low-speed expansion port 114. The low-speed expansion port 114, which may include various communication ports (e.g., USB, Bluetooth, Ethernet, wireless Ethernet), may be coupled to one or more input/output devices, such as a keyboard, a pointing device, a scanner, or a networking device such as a switch or router, e.g., through a network adapter.

The system 130 may be implemented in a number of different forms, as shown in FIG. 1 . For example, it may be implemented as a standard server, or multiple times in a group of such servers. Additionally, the system 130 may also be implemented as part of a rack server system or a personal computer such as a laptop computer. Alternatively, components from system 130 may be combined with one or more other same or similar systems and an entire system 130 may be made up of multiple computing devices communicating with each other.

FIG. 1 also illustrates a user input device 140, in accordance with an embodiment of the invention. The user input device 140 includes a processor 152, memory 154, an input/output device such as a display 156, a communication interface 158, and a transceiver 160, among other components. The user input device 140 may also be provided with a storage device, such as a microdrive or other device, to provide additional storage. Each of the components 152, 154, 158, and 160, are interconnected using various buses, and several of the components may be mounted on a common motherboard or in other manners as appropriate.

The processor 152 is configured to execute instructions within the user input device 140, including instructions stored in the memory 154, which in one embodiment includes the instructions of an application that may perform the functions disclosed herein. The processor may be implemented as a chipset of chips that include separate and multiple analog and digital processors. The processor may be configured to provide, for example, for coordination of the other components of the user input device 140, such as control of user interfaces, applications run by user input device 140, and wireless communication by user input device 140.

The processor 152 may be configured to communicate with the user through control interface 164 and display interface 166 coupled to a display 156. The display 156 may be, for example, a TFT LCD (Thin-Film-Transistor Liquid Crystal Display) or an OLED (Organic Light Emitting Diode) display, or other appropriate display technology. The display interface 156 may comprise appropriate circuitry and configured for driving the display 156 to present graphical and other information to a user. The control interface 164 may receive commands from a user and convert them for submission to the processor 152. In addition, an external interface 168 may be provided in communication with processor 152, so as to enable near area communication of user input device 140 with other devices. External interface 168 may provide, for example, for wired communication in some implementations, or for wireless communication in other implementations, and multiple interfaces may also be used.

The memory 154 stores information within the user input device 140. The memory 154 can be implemented as one or more of a computer-readable medium or media, a volatile memory unit or units, or a non-volatile memory unit or units. Expansion memory may also be provided and connected to user input device 140 through an expansion interface (not shown), which may include, for example, a SIMM (Single In Line Memory Module) card interface. Such expansion memory may provide extra storage space for user input device 140 or may also store applications or other information therein. In some embodiments, expansion memory may include instructions to carry out or supplement the processes described above and may include secure information also. For example, expansion memory may be provided as a security module for user input device 140 and may be programmed with instructions that permit secure use of user input device 140. In addition, secure applications may be provided via the SIMM cards, along with additional information, such as placing identifying information on the SIMM card in a non-hackable manner. In some embodiments, the user may use the applications to execute processes described with respect to the process flows described herein. Specifically, the application executes the process flows described herein.

The memory 154 may include, for example, flash memory and/or NVRAM memory. In one aspect, a computer program product is tangibly embodied in an information carrier. The computer program product contains instructions that, when executed, perform one or more methods, such as those described herein. The information carrier is a computer- or machine-readable medium, such as the memory 154, expansion memory, memory on processor 152, or a propagated signal that may be received, for example, over transceiver 160 or external interface 168.

In some embodiments, the user may use the user input device 140 to transmit and/or receive information or commands to and from the system 130 via the network 110. Any communication between the system 130 and the user input device 140 (or any other computing devices) may be subject to an authentication protocol allowing the system 130 to maintain security by permitting only authenticated users (or processes) to access the protected resources of the system 130, which may include servers, databases, applications, and/or any of the components described herein. To this end, the system 130 may require the user (or process) to provide authentication credentials to determine whether the user (or process) is eligible to access the protected resources. Once the authentication credentials are validated and the user (or process) is authenticated, the system 130 may provide the user (or process) with permissioned access to the protected resources. Similarly, the user input device 140 (or any other computing devices) may provide the system 130 with permissioned to access the protected resources of the user input device 130 (or any other computing devices), which may include a GPS device, an image capturing component (e.g., camera), a microphone, a speaker, and/or any of the components described herein.

The user input device 140 may communicate with the system 130 (and one or more other devices) wirelessly through communication interface 158, which may include digital signal processing circuitry where necessary. Communication interface 158 may provide for communications under various modes or protocols, such as GSM voice calls, SMS, EMS, or MMS messaging, CDMA, TDMA, PDC, WCDMA, CDMA2000, or GPRS, among others. Such communication may occur, for example, through radio-frequency transceiver 160. In addition, short-range communication may occur, such as using a Bluetooth, Wi-Fi, or other such transceiver (not shown). In addition, GPS (Global Positioning System) receiver module 170 may provide additional navigation—and location-related wireless data to user input device 140, which may be used as appropriate by applications running thereon, and in some embodiments, one or more applications operating on the system 130.

The user input device 140 may also communicate audibly using audio codec 162, which may receive spoken information from a user and convert it to usable digital information.

In accordance with an embodiments of the invention, the components of the system environment 100, such as the system 130 and the user input device 140 may have a client-server relationship, where the user input device 130 makes a service request to the system 130, the system 130 accepts the service request, processes the service request, and returns the requested information to the user input device 140, and vice versa. This relationship of client and server typically arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.

It will be understood that the embodiment of the system environment 100 illustrated in FIG. 1 is exemplary and that other embodiments may vary. As another example, in some embodiments, the system environment may include more, fewer, or different components.

Likewise, in some embodiments, some, or all of the portions of the system 130 may be separated into two or more distinct portions.

In the field of information security, access control is the selective restriction of access to a particular resource within a distributed network. Typically, general access control includes authentication, authorization, and review. The authentication portion of access control, among other things, includes user identity verification. In some embodiments, the identity verification process may be multi-factor authentication, i.e., require the user to present two or more pieces of evidence (or factors), depending on the type of access requested by the user. The type of access may determine the verification protocol to be implemented. Each verification protocol may have specific requirements that need to be met by the user for successful identity verification. As such, when a user submits a request to access resources within a distributed network, the system may be configured to determine the type of access requested, and accordingly implement the applicable verification protocols.

In some embodiments, the verification protocols may be implemented using one or more access management tools such as password-management tools, dynamic-password provisioning tools via authentication channels, security-policy enforcement applications, reporting and monitoring applications, identity repositories, and/or any applicable access management tools. Each of these tools are configured in a specific manner unique to each user based on user characteristics, the type of access to the resources, the specific resources involved, and/or the like. In some embodiments, the verification protocols (primary verification protocol, secondary verification protocol, and/or the like) may be created as part of the user portfolio generated for the user by the entity when first integrating the user (as a new employee) into the entity or familiarizing the user (as a new client or customer) with the entity's resources. In some embodiments, to integrate the user into the entity or familiarize the user with the entity's resources, the system may be configured to register the user. During this registration process, the system may be configured to define the verification requirements, i.e., the authentication channels for each verification protocol based on the type of access requested by the user. Accordingly, the system may be configured to electronically receive, from the user input device, a pre-registration request for access to resources within a distributed network, wherein the access comprises one or more access types. In response, the system may be configured to determine one or more authentication channels for the user based on at least the one or more access types. For each authentication channel, the system may be configured to retrieve, from the user input device, authentication channel information. Once retrieved, this information may be stored in the identity repository. For example, the authentication channel may be a communication medium such as telecommunication channel, an electronical mail communication channel, a voice over Internet Protocol (voIP) channel, and/or the like. For each authentication channel, the authentication channel information may be a unique identifier that identifies the user in that channel, such as a telephone number, an e-mail address, a voIP address, and/or the like.

In some embodiments, for each authentication channel, the system may be configured to generate an NFT that is to be used by the identity verification engine to verify the identity of the user when the user requests access to resources. Accordingly, the system may be configured to electronically receive, from the user input device, a request to generate non-fungible tokens (NFTs) for each authentication channel. In response, the system may be configured to initiate an NFT engine on the authentication channel and any associated authentication channel information for that authentication channel received from the user. For example, the telecommunication channel (authentication channel) and a mobile device number of the user (authentication channel information). Using the NFT engine, the system may be configured to generate NFTs for each authentication channel. Each NFT will include, in its many metadata layers, information associated with the authentication channel and any associated authentication channel information. In response, the system may be configured to record the NFTs on a distributed ledger.

In some embodiments, to record an NFT on the distributed ledger, the system may be configured to generate a new transaction object (e.g., block) for the NFT. Each transaction object may include the NFT for the resource, a nonce—a randomly generated 32-bit whole number when the transaction object is created, and a hash value wedded to that nonce. Once generated, the NFT is considered signed and forever tied to its nonce and hash. Then, the system may be configured to deploy the new transaction object on the distributed ledger. In some embodiments, when new transaction object is deployed on the distributed ledger, a distributed ledger address is generated for that new transaction object, i.e., an indication of where it is located on the distributed ledger. This distributed ledger address is captured for recording purposes. In response, the system may be configured to generate a notification indicating that the new transaction object has been created for the NFT in the distributed ledger. As part of the notification, the system may be configured to include the distributed ledger address. In response, the system may be configured to transmit control signals configured to cause the user input device of the user to display the notification.

Once registered, during the pendency of the user's relationship with the entity, the user may request to access specific resources within the distributed network. Accordingly, the system may be configured to electronically receive, from a user input device, a request from a user to access resources. The request typically includes a specific access type, i.e., first access type. In response, the system may be configured to initiate the identity verification process. As described herein, the identity verification process may be multi-factor authentication that requires the user to present two or more pieces of evidence (or factors), depending on the type of access requested by the user. In specific embodiments, where the multi-factor authentication requires two pieces of evidence, the identity verification process may include a primary verification protocol and a secondary verification protocol. During the identity verification process, the system may be configured to first initiate the primary verification protocol, and on successful verification of user identity using the primary verification protocol, initiate the secondary verification protocol. Accordingly, in some embodiments, the system may be configured to initiate, using the identity verification engine, the primary verification protocol in response to receiving the request, wherein initiating further comprises prompting the user to present one or more authentication credentials. In response, the system may be configured to electronically receive, from the user input device, the one or more authentication credentials in response to the prompt. Next, the system may be configured to determine that the one or more authentication credentials meets one or more requirements associated with the primary verification protocol. In response, the system may be configured to determine that the user has satisfied the primary verification protocol. In some embodiments, if the primary verification protocol fails, i.e., if the authentication credentials do not meet the requirements associated with the primary verification protocol, the system may be configured to deny the user request to access the resources.

Having satisfied the requirements of the primary verification protocol, the system may then be configured to initiate, using the identity verification engine, a secondary verification protocol via the first authentication channel. In one aspect, the system may be configured to determine that the secondary verification protocol is to be implemented using a first authentication channel, as determined based on at least the first access type. In some embodiments, in response to determining the identity of the user is to be verified using the first authentication channel, the system may be configured to determine whether the first authentication channel is a valid authentication channel and free from potential exposure.

FIG. 2 illustrates a process flow for secure channel selection for multi-factor authentication using non-fungible electronic resources 200, in accordance with an embodiment of the invention. As shown in block 202, the process flow includes triggering an authentication channel validation engine to validate the first authentication channel. Next, as shown in block 204, the process flow includes retrieving, from an identity repository, authentication channel information associated with the first authentication channel. Next, as shown in block 206, the process flow includes determining, using the authentication channel validation engine, that the user has a non-fungible token (NFT) for the first authentication channel.

Next, as shown in block 208, the process flow includes retrieving, from one or more metadata layers of the NFT, authentication channel descriptors associated with the first authentication channel. In some embodiments, the authentication channel descriptors may include authentication channel information for the authentication channel represented by the NFT. If the authentication channel represented by the NFT is the first authentication channel, then the authentication channel descriptors must match the authentication channel information associated with the first authentication channel.

Next, as shown in block 210, the process flow includes comparing the authentication channel information with the authentication channel descriptors to determine a match. Next, as shown in block 212, the process flow includes determining, using the authentication channel validation engine, that the first authentication channel is valid based on at least the match. Having validated the first authentication channel, the system may then be configured to resume the verification of user identity via the first authentication channel.

Once the first authentication channel is validated, the system may then be configured to transmit a one-time code to the user via the first authentication channel using authentication channel information associated with the first authentication channel. In response, the system may be configured to electronically receive, from the user input device, a user input reproducing the one-time code. Once the code is received from the user, the system may then be configured to determine that the user input reproducing the one-time code matches the one-time code initially transmitted to the user using the authentication information associated with the first authentication channel. In response, the system may be configured to determine that the user has satisfied the secondary verification protocol. Once the user has satisfied the first verification protocol and the second verification protocol, the system may be configured to authorize the request from the user to access the resources.

Typically, NFTs are unique and have only a single owner at a time. For example, the NFT for the first authentication channel is associated only with the user. However, it is not uncommon for an identity verification process whose secondary verification protocol is configured to validate the identity of two or more users (who are often related) via the same authentication channel. For example, a household may have multiple users with individual accounts the same entity but have assigned to use the same authentication channel for the identity verification process, i.e., secondary verification protocol. In such cases, each user may be associated with a fractional NFT and share their association with the first authentication channel. To allow for such a fractional NFT ownership, token standards such as ERC-721 are rewritten. Specifically, the ownership functions of the token standards are re-written to indicate, under “Ownerof” the addresses of all the owners of the NFT, i.e., all the owners of the fractional NFTs that make up the original NFT for the first authentication channel.
